Will smart virtual assistants take our jobs or make them more fulfilling?

Reports that robots, automation and artificial intelligence are going to put millions of us out of work may sound troubling, but should we believe them? That largely depends on whether we're technology optimists or pessimists. In our Future of Work series we look at how jobs might change in the future.

The Snewing family lived in 62 Falkner Street, Liverpool, for more than four decades. They were saddlers working in the late 19th and early 20th centuries. And while the horse-drawn economy dominated, they enjoyed a brisk trade.

These days algorithms dictate the automated trading of trillions of dollars' worth of assets in the financial markets. Artificially intelligent chatbots are taking over from humans in call centres. And soon, planes and cars could be operating autonomously, putting in jeopardy the livelihoods of those who drive professionally.

Robots have been doing the repetitive drudge work in our factories for decades. But now they can flip burgers, flick away unripe tomatoes on a high-speed sorting machine using image recognition, lay bricks, even co-operate to open doors and escape.

Giant 3D printers can make houses out of concrete in a fraction of the time humans can.

The International Federation of Robotics says in manufacturing there are now 74 robot units per 10,000 employees on average, compared with 66 units in 2015. The highest growth rate is in Asia, China in particular.

And software automation, informed by machine learning and artificial intelligence (AI), will have a profound effect on our workplaces and the jobs we do.

Research firm Gartner predicts that by 2020, 85% of questions will be answered by virtual assistants.

When you think that a huge telecoms company like AT&T employs about 100,000 call centre agents to look after its 120 million customers, that's a lot of jobs that could disappear pretty quickly.

But the cost-savings are too big for large corporations to ignore. And they say customer satisfaction increases as these chatbots learn from the millions of previous customer conversations and become smarter.

Some experts fear that self-replicating AI could run out of control

Consultancy Accenture says 81% of executives it interviewed think that within two years AI will be working next to humans in their organisation as "a co-worker, collaborator and trusted adviser".

But McKinsey also acknowledged that this new technology "will also create new occupations that do not exist today, much as technologies in the past have done".

Could the saddler of the past ever have imagined the roles of car mechanic, smartphone app developer or drone pilot?

The Industrial Revolution from the late 17th Century onwards saw mechanisation sweep through many industries. Farming in particular, which accounted for around 50% of all jobs across Europe, saw that percentage dwindle to less than 5% now.

Such upheaval was undoubtedly painful for those unable to adapt, but new types of employment came along eventually.

More recently, there have seismic changes to the global economy. In the last 30 years, we've had digital transformation, the rise of the internet, globalisation. But figures from the World Bank show that global unemployment as a percentage of total labour force has actually fallen from 6.1% in 1991 to 5.8% in 2017, despite the population rising from 5.4 billion to 7.6 billion over the same period.

"This is an evolution of work - the type of work we do will change," says Ian Barkin, co-founder of Symphony Ventures, an RPA specialist with clients such as Lloyds Banking Group and US payroll giant ADP.

Polycom boss Mary McDowell thinks new technologies will make us more productive

"RPA doesn't have to lead to a culling of staff, it can empower them and unleash their creativity. It's freeing them from doing the unproductive stuff."

Mary McDowell, chief executive of video-conferencing provider Polycom, envisages a time where AI will effectively run virtual meetings for us, using facial recognition to identify who's speaking and calling up relevant documents and statistics to support points being made.

"The management of sound and video will be so much better," she says. "Participants will feel like they're actually present and augmented reality will help us collaborate and annotate documents much more productively.

"Meetings will be about the ideas, not the mechanics. Without technical barriers we can focus on the work at hand, whether that's providing telemedicine or distance learning services."

But even the optimists admit that as low-skilled jobs disappear, people will need to learn new skills to compensate.

"This calls on us all to focus on up-skilling," says Mr Barkin. "There's an urgent need for education reform - people need to learn design thinking, creativity, analytics, programming."

Research by job site Indeed finds that in the last three years demand from UK employers for AI specialists has almost tripled.

"Technology can lead to job reductions, but it doesn't have to. This could be a huge good news story," concludes Mr Barkin.

Just don't carry on making saddles when the car is driving down the street towards you.

In the rest of this series we will look at the new types of job that could emerge in the age of robots, AI and automation.
